Abstract: Tartrazine yellow dye is an artificial dye used worldwide and widely applied to processed foods, such as solid soft drink preparations (PSR), known as juice powder. PSR, despite not being a healthy option due to the large amount of sugar and additives in its composition, is a very common product in society's homes, due to its practicality and low cost. The present work aimed to determine the concentration of tartrazine yellow dye in PSR of different flavors and brands by UV/Vis spectrophotometry and verify whether it is within the limit recommended by legislation, as well as measuring its pH, electrical conductivity and total soluble solids content (TSS). ). For determination, an analog spectrophotometer was used. The concentration of the dye found in all brands meets the minimum limit required by ANVISA. The need to implement a minimum limit for the TSS content was also considered, to reduce damage to health in the long term, as there is no concern about controlling the addition of sugars in a product basically made up of additives, with no function of nourish.
